lSpecification of Letters Patent.

Application led December 4,1912. Serial No. 734,833.

To all whom 'it may concern:

Be it known that l, EUGENE BoUnmE'r, a citizen of France, residing at Long Island City, in the county of Queens and State of New York, have invented certain new and useful Improvements in Aeronautical Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in aeronautical apparatus and has particular referencelto aeroplanes and more particularly to a tri-plane.

In the accompanying drawings I have illustrated in plan view in Figure 1 one application of my invention with arts omitted. Fig. 2 is a front elevation of) the same. y Fig. 3 .is a detail of. one ofthe ribs of one of the surfaces. Fig. 4 is a detail of controlling means for operating some of the balancing surfaces, and Fig. 5 is a detail of a modification in perspective.

5--6 are the upper mainv supporting surfaces, 7 8 are the intermediate supporting surfaces, 9-10 are the lower main supporting surfaces, and 11 are the connecting bars or rods forming the .tri-plane structure.

12--13 are parallel longitudinally extending bars of the framework connecting the tail section comprising the surfaces 17 and 18 are lateral surfaces connected t the longitudinal bars 12 and 13 which may be used for maintaining equilibrium as will be hereafter more fully described.

19 is a fixed intermediate surface just forward of the tail.

20 is the elevator pivoted upon the bars 21--22 and may be inclined by any suitable means such as the connecting wire 23 within convenient reach of the o erator.

24 is the hand wheel a jacent to the seat 25 and connected with the rudder 26 by the wires 27-27' as shown so that by rotating the wheel 24 the rudder 26 may-.be operated in the usual well known manner, and by throwing the wheel 24 forward and backward the elevator 20 may be raised and lowered by the connecting wire 23 also in the usual well known manner.

The surfaces 17 and 18 are connected by the rod 28 as shown to advantage in Fig. 4 and this rod is connected by wires 29-29 to the lever 30 at the right of the operators seat so that by operating said lever the sur- 'faces 17-18 may be raised on one side and lowered on the other as shown in dotted outline in Fig. 4, thus serving to maintain equilibrium. The ltail surface 14-15-16 is mounted upon the axis 31 which in turn isA connected by the wire or cable 32 to the lever 33 at theleft side Iof the operators seat which when thrown forward or rearward serves to elevate or depress the tail according to the -will of the operator.

At the lateral extremities of the intermediate supporting surfaces 7--8 suitable ailerons or balancing surfaces such as 34-35 may be pivotally mounted as shown and connected by any suitable aneans such as they bar 36 which in turn Iis .pivoted to the bar 37 pivoted to the lever `88, pivotally mounted in the bracket 39 and within convenient reach of the operator, so that by `shifting the lever 38 the ailerons can be readily operated.

In Fig. 3 the preferred cross sectional curve of the supporting surfaces is shown. In Fig. 1 the intermediate surface isfshown in dotted outlines as indicated by the reference character 7 on the left hand side of said figure. On the right hand side of said figure the lower supporting surface is shown in dots and dashes'and indicated by the reference character 10.,

40-41 are pontoons having cut-away por- 'tions at the center to admit of the wheels 42-43 and connected by the bar 44. This bar is in turn connected with the bar 45 and the levers 46, 47 and 48 so that by lifting the lever 48 the bar 47 and its connecting bar 46 are rotated which lifts the rod 45 and the connecting bar 44, raising the pon'- toons clear of the wheels 43so that said wheels can run upon the ground when the pontoons are not in use.

49 and 50 are suitable providedr with oil, and 51 isa smaller tank in the upper part of the machine into which 4 the oil may be forced to Supply the engine 52.

53 is the propeller. Referring now to Fig. 5, 54 indicates an intermediate surface which may be substitanks which may betuted for the surface 7-8 although it is pref- 55 on either side of the machine can be tilted for balancing purposes.

Of course it will be understood that various modifications may be made without departing from the spirit of the invention as set forth in the claims.

I claim:

l. In a triplane, an upper supporting surface having rearwardly projecting lateral tips, an intermediate supporting surface having controlling surfaces mounted in the lateral extremities thereof, and a rectangular lower supporting surface.

Q. In a triplane, an upper supporting sur# face having rearwardly projecting lateralA tips, an intermediate supporting surface having controlling surfaces mounted in the lateral extremities thereof, and a rectangular lower supporting surface, said intermediate surface of less width than said upper supporting surface, and said lower supporting surface of less width than said intermediate supporting surface.

3. In a triplane, an upper supporting surface having rearwardly projecting lateral tips, an intermediate supporting surface having controlling surfaces mounted in the lateral extremities thereof, and a rectangular lower supporting surface, saidsurfaces having substantially fiat forward and rearward portions and an arched central portion extending transversely of the same.

4. In' a triplane, an upper supporting surface having rearwardly projecting lateral tips, an intermediate supporting surface having controlling surfaces mounted in the lateral extremities thereof, a rectangular lower supporting surface and an elevator pivotally mounted in the center of said upper supporting surface and at the forward portion of the same adapted to be adjusted upon an aXis transverse 'to' the line of flight.

In testimony whereof I affix signature i in 'presence of twolwitnesses.
